What do you guys think about the 180 GH ASICS? They are priced at 1.16 BTC and you get them in 4-5 days I think.
Difficulty is the biggest problem. Not the 1-3% fee. The electricity might also be a factor especially for small non USB ASICS.
I run several 180Gh asic antminers with no problems, although I run them wired and not wireless. Power depends on the PS you have connected to it, you can run 2 antminers on a powerful enough power supply. I use an 850W to power a single antminer which pulls about 4amps at the PDU. If I add an miner to my farm, it only takes about 3 days before its profitable (all my miners are now profitable). Some people overclock them, but I run them vanilla, I've always believed in if it works, why mess with it. Also, some people will add an extra fan to them as well, but I leave them alone.
